MULTI-MECHANISTIC CHANNELING WITHIN A BIOCATALYTIC CASCADE FOR THE PRODUCTION OF 1,3-DIAMINOPROPANE

Resumen de: US20260317794A1

0000 Described herein is a one-pot, four-enzyme cascade of enzymes, three bound to quantum dots with one enzyme free in solution, for the conversion in vitro of fumarate to 1,3-diaminopropane. The cascade operates via two distinctly different enzymatic channeling mechanisms which simultaneously function to increase the overall rate. The first three enzymes of the pathway (AspB→LysC→Asd) were able to engage in channeling in a nanoparticle displayed format, but addition of the last two enzymes to this pathway in this format (AspB→LysC→Asd→Dat→Ddc) did not result in complete channeling through the entire pathway to the final diaminopropane product. Surprisingly, replacement of the last two enzymes (Dat→Ddc) with a naturally occurring fused Dat-Ddc hybrid (Daba) provided for full channeling in this system (AspB→LysC→Asd→Daba).
